heres the deal. im tired of trying to get the 310s to run right, so i went to put the stock injectors back in. they worked fine when i took them out. but now, the car doesnt want to idle and if you give the car more than 1/4 throttle, it studders, pops, and just plain sucks. i put the 310s back in, ran like it did with the 310s before, put the stockers back in, and doesnt want to idle and studders and **** again. sprayed wd-40 all over the intake mani, idle doesnt change, so there isnt a vac leak. i might go to the junkyard tomorow and pull some stock injectors and see if it helps. any idea what the deal is?

maybe you fucked up the afm.

i dont see how. if different injectors dont work, i might try and snag another afm to try.

that might be an option, need to call back my rx7 friend to see if he has an extra too.

How do you know if its all of them? What if its just one? Can you tell if its a particular one?

Pull each injector plug and see if there's a difference in how it runs.

^What Jwarriner said.

Just based off the title, yes injectors can go bad. I had one on my Eclipse start intermittently (30 seconds over and hour of driving) failing then become progressively worse over the course of 2 months until it completely failed.

Thats safe at idle right?

I ask because, I have some 460's on the way and even though the guy said they were cleaned and flow tested 500 miles ago they havent been used for a while, so I need a way to make sure they are all in order.

oh, forgot to add, the only way i can get it to idle with the stock injectors now, is with the afm screw almost all the way turned in.

I had the same thing happen with the same size injectors and FMU. You more than likely fouled your plugs due to a super rich condition. Swap back to the old injectors, install new plugs, and see what happens.

the problem is with the 310s, it runs ok, just really rich everywhere. and the stock injectors, it doesnt want to run for ****. i have swaped back and forth several times. is there a way to test the AFM?
